Calculus II as a high school senior online

I am currently a high school junior and will be a senior next year. This year I took calculus AB, the highest level math class at my high school. Next year I want to be able to take the calculus BC AP test and as far as I know, that test is over both calculus I and II (I’m not 100% sure on this so if I am wrong please correct me). Since calculus AB is calculus I (again, as far as I know), I need to take calculus II in order to know the material for the BC AP test. I live in a small town and the community college here doesn’t offer calculus II, how can I take this course online? It doesn’t necessarily need to be for high school or college credit, but just so that I can learn the material.
